A researcher hypothesizes that the average number of sports that a college offers for males is greater than the average number of sports offered for females. A random sample of 50 colleges found a mean of 8.6 sports for men and 7.9 sports for women. The population standard deviation is known to be 3.3 for both groups. At α=0.10, is there enough evidence to support the claim?
